The total density of states N*(*E) is a well known concept in electronic structure theory of infinite systems (crystals). with k ~ 0, therefore, if you have a dispersion curve, the only thing you need to look at, is the frequencies around k = 0.
volume times the k space state density:V g k dk k dkS S ªº «»¬¼ (3) Each k state can hold 2 electrons (of opposite spins), so the number of electron states is:V g k dk k dkS S ªº «»¬¼ (4 a) Finally, there is a relatively subtle issue.
